About

Swagger Editor is an open-source web app in the developer tools category (openapi). It opens in your browser, so there is nothing to install. You provide openAPI YAML/JSON and get docs preview and errors. It needs no account. It is a plain tool: no AI model is involved. The source code is public on GitHub (swagger-api/swagger-editor).
